Is there any published work on hiding subliminal messages in pictures? It seems like that would be really easy.
Read R. Key's _The Clam-Plate Orgy_ for information on how advertising companies (cigarette ana alcohol companies especially) add little airbrushed renditions of subliminally pleasing sex scenes, with intent to stimulate purchase of the product. Its been done for almost 50 years now, and started with the tachistoscope used in movie theatres to get people to consume popcorn and Coca-Cola(tm) in great quantities. Sales went up by 60%.
Big brother comes and tells you that you are not allowed to encrypt anything, and you say that you used a random number generator for this new form of art that appears to be total oblivion, but really represents a new way of looking at the meaning of life. Meanwhile, your pal on the other hand runs it through a processor and decrypts the message.
If you tried to sell the idea that your random number generator is random, then the government would come back and say that there is no way to determine random numbers, and if there was, they'd ask you why you would be able to run it through a processor and decrypt it. But then again, laws on subliminal information are practically null, and those that do exist are never enforced, thanks to Big Business influence-peddling. Alex Reynolds
